This is a new audio edge memorization method I came up with. The aim of the method is to produce a sequence of audio pairs that is as short and easy to remember as possible on average, without being too hard to learn. I also wanted some properties, such as edge orientation, to be immediately obvious from the sound. Lastly, I wanted the sound as a whole to be unambiguous, that is, it should always be possible to deduce where the pairs start and end, even when pronounced together with no pause in between. I've done a lot of experimentation with different variants, and this is the final version that I'm quite satisfied with.

First of all, every edge (except the buffer) is given a consonant and a vowel. Note that I'm referring to the actual sounds, not the letters. I think most people are familiar with at least 11 consonants, so that part shouldn't be a problem (personally, I chose SFNMLRKGTDP). However, 11 vowels is a lot, and even though I'm familiar with about 20 vowel sounds because of the languages I speak, not all of them are equally good. I did a lot of experimentation, and what worked best for me was to use only the 5 Japanese vowels (AIUEO), each with two different pitches (low and high), yielding a total of 10 different vowel sounds. For the last one, I used a trick that I'll explain later.

Next, I'll explain how to make audio pairs. I like to think of it this way: For the first target, we simply pick the consonant of the corresponding edge piece if it's oriented, or the vowel if it's not oriented. Then we add the sound of the second target of opposite category, and we also add the letter H (which I'll explain in a moment) next to the vowel if the second target is not oriented. In other words, we either get a consonant + vowel (+ H) or a (H + ) vowel + consonant pair. If there's no H in the pair, it's pronounced normally. H + vowel can be pronounced normally as well, but I'll explain some optimizations later. Also, vowel + H is simply the vowel pronounced twice as long. Personally, I also change the vowel slightly into a similar but different sound. This makes sense in Swedish, but simply using the exact same vowel works fine as well.

Lastly, I'll discuss some optimizations. First of all, it's possible to remove one vowel (so that you only need 10), since whenever we have that vowel in a pair, we can simply replace it with the corresponding vowel of the consonant in the pair. This is possible because the new pair we create consists of the consonant and vowel of the same edge, which would otherwise not be used (as long as you don't memorize flips with audio pairs). Also, when pronouncing pairs together, it's possible to replace consonant + H combinations with a long version of the consonant (pronounced equally long as a short vowel), which can make the sound flow better.

Doing it this way will produce a short melody that works really well for me at least. I'm not sure if this would be possible to use in a competition though, where you have to be quiet :p

I think I'll stop here, but let me know if there's anything unclear about the method, or if you have anything else you'd like to say/ask about it :)

I struggle to understand written explanations, can you give a few examples of what you mean.

I am genuinely interested is your concept, I'm not really understanding it though.

Sure! Giving some examples is a great idea. Thank you for the suggestion.

I'll start by being more specific about the letters. There are many combinations that work equally well, but I'll chose this for the examples:

UF/FU = buffer
UB/BU = S/a
DF/FD = F/A
DB/BD = P/-
UR/RU = N/i
UL/LU = M/I
DR/RD = L/e
DL/LD = R/E
FR/RF = K/o
BR/RB = G/O
FL/LF = T/u
BL/LB = D/U

Here, lowercase vowels are pronounced with a low pitch, and uppercase vowels are pronounced with a high pitch, and - is the redundant vowel that isn't used, as explained in the original post (you can also choose to use an actual vowel for it and treat it just like the others instead).

Now we're ready to look at some examples. I'll include a recording of me pronouncing the full memo of the examples, and if you want to follow along, do the scrambles in your color orientation.

Scramble 1: B' L2 R2 B D2 U2 L2 F' D2 L2 U2 B2 D B L' R U' L' F U2 R2
Memo: FL-RU + DR-UB + LB-FR + UL-DB + RB-BD (+ DF flip memorized visually)
Audio: TiiLaUKMIHOP (Tii + La + UK + MI + HOP)

Scramble 2: D' L2 D B2 D F2 U' B2 R2 B' D' R2 U B' U R' D L
Memo: LF-BL + RB-LU + UB-DF + UR-BD + DR-DL + FR-UR
Audio: uDDOMSANiiLEKi (uD + HOM + SA + Nii + LE + Ki)

Scramble 3: F' U2 B2 D2 B2 D' L2 R2 D' L2 R' B2 L2 D' B' F' D2 F2 R'
Memo: LB-DL + LF-BR + UL-RF + DF-BD + DR-BU (+ UR flip memorized visually)
Audio: URuGMooFAALaa (UR + uG + Moo + FAA + Laa)

Scramble 4: R' L2 B2 D2 U' F2 U R2 B2 L2 U F D' U R B D2 L' R2
Memo: DF-RU + FL-DR + LU-DL + UB-RF + UB-DB + BR-DB (+ BL flip memorized visually)
Audio: FiiTeIRSooSaGO (Fii + Te + IR + Soo + Sa + GO)

Note that "uD + HOM" becomes "uDDOM" in the second example. By "DD", I mean a long "D", which in this case is a so called glottal stop plus a "D".

I'll also explain in more detail how to convert all of the pairs into audio pairs in the first example. First off, we have the pair FL-RU. Since the first target FL is the oriented side of the corresponding FL/LF edge, we use it's consonant "T", and the vowel of the second target RU, which is "i". Furthermore, since RU is the non-oriented side of the UR/RU edge, we make the vowel sound twice as long, which I'll denote by writing the same vowel two times. The final audio pair then becomes "Tii". Next, we look at the second pair DR-UB. Since both DR and UB are the oriented sides of the corresponding edges, we use the consonant of the first target DR and the vowel of the second target UB, resulting in the audio pair "La". For the third pair LB-FR, the first target LB is not oriented but the second target FR is, so we pick the vowel of LB and the consonant of FR, resulting in the audio pair "UK". For the fourth pair UL-DB, once again, both targets are oriented, which means we pick the consonant of the first and the vowel of the second. This time however, we have the special vowel "-" which we simply replace with the vowel of the first target, that is, "I", resulting in the audio pair "MI". For the last pair RB-BD, both targets are non-oriented, which means we pick the vowel of the first, the consonant of the second and lastly prepend "H", resulting in "HOP".

I hope the examples cleared things up! Please don't hesitate to ask if there's still something unclear :)

Thank you, that made a lot more sense. The audio was a great help as well. Had to read your last paragraph carefully and slowly, but I do think I understand what you mean.

It's an interesting concept, and using differences in how you intonate the vowels means you can have more information than just a sound. It's certainly more musical than the audio I'm currently using for edges. Great idea !!

Thank you for the feedback! Yeah, I'm not sure how practical this method will be for speedsolving, but I think intonation can be a great tool that can be implemented in other methods as well. For example, If you're using Speffz, you could replace Q with an "A" with high pitch. Since the normal "a" with low pitch is on the piece, you'll never run into weird aA or Aa combinations, and except the intonation, you can just treat it like a normal A.

Or if you for example don't like vowel + Q combinations, you could just omit the Q and change the intonation of the vowel.

That was just a couple of random ideas, but there are definitely other ways of utilizing intonation as well!
 
Also, I completely forgot to mention it, but you can also replace the high pitch with something else, like stamping with your foot. If you stamp quietly, it might be possible to use in a competition lol.

This sounds interesting.

Have you used this form of memorization successfully in a competition?

Sorry, I've actually never been to a competition yet. Also, I haven't done much experimentation with stamping, since I personally found pitch easier to recall correctly. However, I have done a few successful solves at home with the pitch version (I've just started practicing it), and while it sometimes requires reviewing at the end to sound good (which admittedly is a weak point), I've had much higher retention rate with it compared to every other audio method I've tried.
